You can parse this in two ways:

Reminds me of the number-line notation you learn about *before*
precalculus (or whatever the value of
$you.schooling.grade[12].class{math}.name is) confuses everything, with
open vs. closed

Actually, I would at first glance think, based on the parens, that:
(1..10)-1
means
((1-1)..(10-1))
means
(0..9)

Since xor is really low frequency, why not make xor mean xor?
$zero = $a xor $a;
$a xor= $b;
$b xor= $a xor= $b xor= $a; # Swap'em
@a ^xor= @b; # Is this right?
